Cushings are feces that accumulate at the end of the colon and are not excreted. From the point of view of the digestive process of food, after the food is chewed and initially digested in the mouth, it passes through the esophagus into the stomach, where it mixes well with gastric acid and various digestive juices, and then enters the intestines, where it passes through the duodenum, the jejunum, the ileum, the cecum, the colon, the sigmoid colon, and the rectum, and is discharged from the body. In the above process, only into the colon, the water in the food residue is absorbed, and the residue begins to gather and form, before it begins to form feces. Therefore, hangover should refer to the accumulation of feces at the end of the colon ready to be excreted from the body. Hangover may appear as stone-like, dry, hard stools or dry, lumpy stools. However, there are some constipated patients whose stools do not show any change in character, but only show difficulty in defecation or a decrease in the number of bowel movements. Patients with these conditions should go to a specialized hospital in time and be actively diagnosed and treated under the guidance of a doctor.
